# NASA Conducts 2nd RS-25 Test in Latest Developmental Series

NASA conducted a second RS-25 single engine hot fire test April 6 to support development and production of engines to help power the agency’s Space Launch System (SLS) rocket on future missions to the Moon. The full-duration hot fire of more than eight minutes (500 seconds) was conducted on the A-1 Test Stand at Stennis. It is part of a scheduled seven-test series designed to provide valuable data for Aerojet Rocketdyne, as it begins production of new RS-25 engines for use after the first four SLS flights.
